113e103bc2 Modify the joint damping input check, and output error message when it doesn't pass the size check. Modify the kuka grasping example accordingly. Setting joint damping in this example was a no-op before. 2017-09-27 15:18:08 -07:00

b1f8eb74a4 bump up shared memory version number
add option to recompute forward kinematics, to be consistent with link velocities in pybullet.getLinkState (..., computeForwardKinematics=0/1), thanks to Jeff Bingham for bringing up this inconsistency

ee30ca93c5 [sharedmemory] Fill-out calculateJacobian command.
The server command processor actually didn't do anything with
the local point that was passed along with the calculateJacobian
command. Added in the necessary bit of math to return the
corresponding jacobian.

Also, fixed a typo in pybullet that was returning the same
jacobian for translation and rotation.

1727e47beb [pybullet] Add calculateJacobian.
* Add the calculateJacobian method to the pybullet API.
* Adjust the shared memory interface to handle fixed/floating bases
  in the calculateJacobian method.
* Fix a few comments.

ee30479a28 add option to log joint torques (due to user applied torques and/or motor torques)
See quadruped.py for an example:
p.startStateLogging(p.STATE_LOGGING_GENERIC_ROBOT, "genericlogdata.bin", maxLogDof = 16, logFlags = p.STATE_LOG_JOINT_TORQUES)

bcc60224f0 all methods (except connect, obviously) have the physicsClientId argument, even if they don't use it. This makes it easier to create a wrapper API to store the physics client. This allows easier multi-threaded versions with multiple Bullet DIRECT instances (or SHARED_MEMORY, TCP, UDP etc).
See for example https://github.com/bulletphysics/bullet3/blob/master/examples/pybullet/gym/pybullet_envs/bullet/bullet_client.py and https://github.com/bulletphysics/bullet3/blob/master/examples/pybullet/gym/pybullet_envs/bullet/minitaur.py
